When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
The processing route of xenotime is similar to that of monazite. 2.5.2 Ion Adsorption Clays. Commercial mining and processing of these types of ores are currently exercised only in China. The REO assay in this ore is too low, and it lies around 0.05–0.2%. Therefore, ore beneficiation does not have much role in the processing route.
